Bassline

A bassline (also known as a bass line or bass part) is the term used in many styles of popular music, such as jazz, blues, funk, dub and electronic, or traditional music, for the low-pitched instrumental part or line played by a rhythm section instrument such as the electric bass, double bass, cello, tuba or keyboard (piano, Hammond organ, electric organ, or synthesizer). It is also used sometimes in classical music. In solo performance, basslines may simply be played in the lower register of any instrument such as guitar while melody and/or further accompaniment is provided in the middle or upper register.
